PLEASE SOMEONE HELPPP A toy truck with a mass of 0.6 kilogram initially coasts horizontally at a constant speed of 2 meters per second. A child drops a beanbag of mass 0.2
kilogram straight down onto the track. Immediately after the collision the objects stick together and the speed of the truck is most nearly:
1.5 m/s
2.0 m/s
0.3 m/s
1.2 m/s
2.4 m/s
